A physician assistant who treated George Zimmerman's injuries the day after he said he shot and killed Trayvon Martin in self-defense testified Friday that she had treated Zimmerman before, and that he told her he'd had been involved with mixed martial arts several times a week.

Lindzee Folgate said she previously treated Zimmerman in August and September 2011. When he returned for treatment on Feb. 27, 2012, with various cuts and a broken nose, Folgate said Zimmerman told her he was in a fight and his head was shoved into the ground.

Lindzee Folgate treated George Zimmerman's injuries the day after the shooting.

On the visit on Feb. 27, 2012, the day after Trayvon Martin was shot, Folgate said Zimmerman told her he was in a fight and his head was shoved into the ground. He also told her he had a weapon and shot his attacker.

Folgate said Zimmerman complained of feeling nauseated upon reflecting what had happened. But she attributed that to psychological factors rather than any physical condition. She also said it appeared his nose was broken, but it was impossible to say for sure, since no X-rays were taken. She recommended he see an ear-and-nose doctor and a psychologist.

When O'Mara asked if abrasions on his head were consistent with someone who had his had slammed into concrete, Folgate said, "it could be consistent, yes."

She also testified that Zimmerman had written on a form reciting his medical history that he was exercising three times a week by doing mixed martial arts, a statement that prosecutor Bernie de la Rionda asked her to repeat.

Folgate said she had treated Zimmerman for previous injuries before. She first encountered him in August 2011, and Zimmerman indicated that he had "difficulty with falling asleep and exercising with MMA, but that has not helped."

She said she also treated Zimmerman in September 2011, and at that time he indicated he was involved in mixed martial arts three days a week.

Sanford Police Officer Tim Smith was the first officer on the scene.

Smith said he was originally called to the Retreat at Twin Lakes to respond to a call about a suspicious person in the neighborhood. He then got an update that shots had been fired as he was entering the community.

Smith testified that when he saw Zimmerman after the shooting, the neighborhood watch volunteer's backside was covered in grass and wetter than his front side, bolstering defense attorneys' contention that Martin was on top of Zimmerman. Smith also said it was dark and raining, and he was using his flashlight.

As he walked to the squad car after he had been handcuffed, Zimmerman told the officer that "he was yelling for help and nobody would come help him," Smith said.

"It was almost a defeated … a confused look on his face," Smith said.

According to Smith, Zimmerman described himself as "lightheaded" during the drive to Sanford Police station, but declined an offer to take him to a hospital. The jury saw video from the Sanford Police Department of Smith taking Zimmerman to police headquarters to be questioned.

Smith submitted evidence he collected at the scene, including Zimmerman's gun, to crime scene technician Diana Smith -- his wife -- who testified on Tuesday.

Stacey Livingston, a Sanford Fire-Rescue paramedic, treated George Zimmerman's injuries.

Livingston said Zimmerman had a swollen, bleeding nose and two cuts on the back of his head an inch long. When O'Mara asked if Zimmerman should have been concerned with his medical well-being because of his injuries, Livingston said, "Possibly."

She also told prosecutor John Guy that Martin was pronounced dead at 7:30 p.m. Sunday, Feb. 26, 2012, a few minutes after she arrived at the scene. As photos of Trayvon Martin's body were shown on a courtroom projector during Livingston's testimony, the teen's mother, Sybrina Fulton, looked away and blinked back tears.

Livingston was the 20th witness called since testimony began Monday.

Ricardo Ayala is a Sanford Police officer who attempted to revive Trayvon Martin.

Ayala was dispatched to the Retreat at Twin Lakes community in response to a call about a suspicious person, which was later updated to shots fired on his way to the scene.

Officer Ayala said when he arrived, Trayvon Martin was lying face down on the ground. He attempted to perform CPR, but Martin was unresponsive.

Ayala said Officer Timothy Smith was at the scene when he arrived and holding Zimmerman at gunpoint. Ayala said it was police protocol to draw their weapons when responding to calls about shots fired. Ayala said Zimmerman was compliant and did everything officers asked. He added he made no further contact with Zimmerman after he was secured.

Jonathan Manalo was the first neighbor to step outside and see what happened with his flashlight after he heard a gunshot.

Manalo, whose wife testified Wednesday, took cell phone photos of a bloodied Zimmerman and Trayvon Martin's body, and those photos were shown to jurors on Friday. Manalo also described Martin's hands as being under his body.

Manalo said Zimmerman didn't appear shocked and acted calmly. After police officers arrived and handcuffed Zimmerman, the neighborhood watch volunteer asked Manalo to call his wife and tell her what happened.

Manalo started to tell Zimmerman's wife that her husband had been involved in a shooting and was being questioned by police when "he cut me off and said, 'Just tell her I shot someone,'" Manalo said.

Under cross-examination, Manalo said when he asked Zimmerman what happened, the neighborhood watch volunteer told him, "I was defending myself and I shot him."

"From what you could tell at that moment, that seemed completely true?" asked defense attorney Don West.

"Yes," Manalo said.

Jonathan Good said he saw one person striking the other while straddling him.

Good, who had perhaps the best view of the struggle between Zimmerman and Trayvon Martin, said it appeared one person was striking the other while straddling him "MMA-style."

However, Good also said he did not see anyone's head being slammed into the concrete sidewalk, which Zimmerman has said Martin did to him.

Good initially testified that it appeared "there were strikes being thrown, punches being thrown," but during detailed questioning Friday, he said he saw only "downward" arm movements being made.

Zimmerman has claimed that he fatally shot 17-year-old Martin last year in self-defense as the teen was banging his head into the concrete sidewalk behind the townhomes in a gated community.

But under prosecution questioning, Good said he never saw anyone being attacked that way during the fight between Zimmerman and Martin.

"I couldn't see that," Good said moments later while being cross-examined.

Good, said he heard a noise behind his home in February 2012, and he saw what looked like a tussle when he stepped out onto his patio to see what was happening.

He said he yelled, "What's going on? Stop it."

Good testified he saw a person in black clothing on top of another person with "white or red" clothing. He said he couldn't see faces but it looked like the person on the bottom had lighter skin. Martin was black and was wearing a dark hoodie. Zimmerman identifies as Hispanic and was wearing a red jacket.

"It looked like there were strikes being thrown, punches being thrown," Good said.

Later, under cross-examination, he said that it looked like the person on top was straddling the person on bottom in a mixed-martial arts move known as "ground and pound." When defense attorney Mark O'Mara asked him if the person on top was Martin, Good said, "Correct, that's what it looked like."

Good also said the person on the bottom yelled for help.

During cross-examination, O'Mara got on his knees to recreate the fighting as he asked Good to walk him through it.

Good was in the middle of dialing 911 inside his townhome when he heard a gunshot, he said.

Greg McKinney works at a video surveillance company that maintains cameras at the Retreat at Twin lakes.

Prosecutor Rich Mantei played two videos from surveillance cameras for McKinney.

One showed what looked like a person walking past a window at the complex's clubhouse, and another showed what looks like someone with a flashlight by the complex's mailboxes.

McKinney said the digital clock on the video was off by 18 minutes, a point O'Mara hammered home by getting McKinney to concede the timing difference was inexact and could be more than 18 minutes.

McKinney also said the front gate cameras were not working on the night of Feb. 26, 2012, because he believes a lawn mower had hit the cables before that night.

No court planned Saturday or July 4

Seminole County court officials announced Thursday that there were currently no plans to continue testimony in the George Zimmerman trial on Saturdays, or during the July 4 holiday next week.

However, court officials added the trial's schedule is subject to change.

The timing of the George Zimmerman trial near the Fourth of July holiday had many wondering whether Judge Debra Nelson would consider holding court on the holiday or on Saturdays in an effort to shorten the jury's sequestration period. The trial is expected to last a total of two to four weeks.

Many have noted that the Casey Anthony murder trial in 2011 did hold half-days in court on Saturdays, and the jury began deliberating on July 4. In both cases, the jurors said they were willing to hear testimony over weekends and the holiday in order to speed up what ended up being a seven-week trial.
